- Speech perception in adolescents with pre-lingual hearing impairment with cochlear implants(2011) SOUZA, Izi Patricia Souza de; BRITO, Rubens de; BENTO, Ricardo Ferreira; GOMEZ, Maria Valeria S. Goffi; TSUJI, Robinson Koji; HAUSEN-PINNA, MarianaProfound hearing loss is a disability that affects personality and when it involves teenagers before language acquisition, these bio-psychosocial conflicts can be exacerbated, requiring careful evaluation and choice of them for cochlear implant. Aim: To evaluate speech perception by adolescents with profound hearing loss, users of cochlear Implants. Study Design: Prospective. Materials and Methods: Twenty-five individuals with severe or profound pre-lingual hearing loss who underwent cochlear implantation during adolescence, between 10 to 17 years and 11 months, who went through speech perception tests before the implant and 2 years after device activation. For comparison and analysis we used the results from tests of four choice, recognition of vowels and recognition of sentences in a closed setting and the open environment. Results: The average percentage of correct answers in the four choice test before the implant was 46.9% and after 24 months of device use, this value went up to 86.1% in the vowels recognition test, the average difference was 45.13% to 83.13% and the sentences recognition test together in closed and open settings was 19.3% to 60.6% and 1.08% to 20.47% respectively. Conclusion: All patients, although with mixed results, achieved statistical improvement in all speech tests that were employed.
- Use of remote control in the intraoperative telemetry of cochlear implant: multicentric study(2019) TANAMATI, Liege Franzini; GOFFI-GOMEZ, Maria Valeria Schmidt; MUNIZ, Lilian Ferreira; SAMUEL, Paola Angelica; WIEMES, Gislaine Richter Minhoto; LIMA, Daniele Penna; CURI, Silvia Badur; ONUKI, Lucia Cristina; QUEIROZ, Carla Fortunato; CAPISTRANO, Ana Karla Bigois; MORET, Adriane Lima Mortari; KIMURA, Marcia Yuri Tsumura; OYANGUREN, Valeria; MAUCH, HerbertIntroduction: The conventional evaluation of neural telemetry and impedance requires the use of the computer coupled to an interface, with software that provides visualization of the stimulus and response. Recently, a remote control (CR220 (R)) was launched in the market, that allows the performance of intraoperative tests with minimal instrumentation. Objective: To evaluate the agreement of the impedance values and neural telemetry thresholds, and the time of performance in the conventional procedure and by the remote control. Methods: Multicentric prospective cross-sectional study. Intraoperative evaluations of cochlear implants compatible with the use of CR220 (R) were included. The tests were carried out in the 22 electrodes to compare the time of performance in the two situations. The agreement of the neural telemetry threshold values obtained from five electrodes was analyzed, and the agreement of impedance was evaluated by the number of electrodes with altered values in each procedure. Results: There were no significant difference between the impedance values. There was a moderate to strong correlation between the electrically-evoked compound action potential thresholds. The mean time to perform the procedures using the CR220 was significantly lower than that with the conventional procedure. Conclusion: The use of the CR220 provided successful records for impedance telemetry and automatic neural response telemetry.

- Result on speech perception after conversion from Spectra ® to Freedom ®(2012) MAGALHAES, Ana Tereza de Matos; GOFFI-GOMEZ, Maria Valeria Schmidt; HOSHINO, Ana Cristina; TSUJI, Robinson Koji; BENTO, Ricardo Ferreira; BRITO, RubensNew technology in the Freedom (R) speech processor for cochlear implants was developed to improve how incoming acoustic sound is processed; this applies not only for new users, but also for previous generations of cochlear implants. Aim: To identify the contribution of this technology - the Nucleus 22 (R) - on speech perception tests in silence and in noise, and on audiometric thresholds. Methods: A cross-sectional cohort study was undertaken. Seventeen patients were selected. The last map based on the Spectra (R) was revised and optimized before starting the tests. Troubleshooting was used to identify malfunction. To identify the contribution of the Freedom (R) technology for the Nucleus22 (R), auditory thresholds and speech perception tests were performed in free field in soundproof booths. Recorded monosyllables and sentences in silence and in noise (SNR = 0dB) were presented at 60 dBSPL. The nonparametric Wilcoxon test for paired data was used to compare groups. Results: Freedom (R) applied for the Nucleus22 (R) showed a statistically significant difference in all speech perception tests and audiometric thresholds. Conclusion: The reedom (R) technology improved the performance of speech perception and audiometric thresholds of patients with Nucleus 22 (R).
- Neurofibromatosis 2: hearing restoration options(2012) MONTEIRO, Tatiana Alves; GOFFI-GOMEZ, Maria Valeria Schmidt; TSUJI, Robinson Koji; GOMES, Marcos Queiroz Telas; BRITO NETO, Rubens Vuono; BENTO, Ricardo FerreiraNeurofibromatosis 2 (NF2) is an autosomal dominant disease in which hearing loss is predominant. Auditory restoration is possible using cochlear implants (CI) or auditory brainstem implant (ABI). Objective: To assess the auditory results of CI and ABI in NF2 patients and review the literature. Methods: Four NF2 patients were prospectively evaluated. They were submitted to tumor resection followed by ipsilateral CI or ABI depending on cochlear nerve preservation. Long term auditory results were described for CI (12 months) and ABI (48 months). Results: All patients achieved auditory perception improvements in their hearing thresholds. The CI patient does not recognize vowels or sentences. The 3 ABI patients discriminate 70% of vowels and 86% in the 4-choice test. One of them does not recognize sentences. The other two recognize 100% of closed sentences and 10% and 20% of open sentences. Conclusion: The choice of implant type to restore hearing to NF2 patients will relay on anatomical and functional cochlear nerve preservation during tumor resection surgery. Although our experience was different, the literature shows that if this condition is achieved, CI will offer better auditory results. If not, ABI is recommended.
